CCD camera is a camera made of semiconductor imaging devices.CCD is the abbreviation of Charge Coupled Device (Charge Coupled Device), thus it has the advantages of high sensitivity, resistance to strong light, small distortion, small size, long life, vibration, etc.
CCD camera works by focusing the image of the subject through the lens onto the CCD chip, the CCD accumulates a corresponding proportion of charge according to the intensity of light.
The CCD camera works by focusing the image of the object being photographed onto the CCD chip through the lens, the CCD accumulates the corresponding proportion of charge according to the intensity of the light, and the charge accumulated by each pixel is shifted outward, point by point, under the control of video timing, and then filtered, amplified and processed to form a video signal output.
The video signal is connected to the video input of a monitor or TV set to see the same video image as the original image. It is a semiconductor imaging device, in order to simplify the power supply of the CCD camera, generally from the external input only a power supply (12V), and various other voltages within the power supply are obtained from the power conversion.
Extended information:
? CCD imaging size commonly used 1/2 "1/3", etc., the smaller the imaging size of the camera can be made smaller. With the same optics, the larger the imaging size, the larger the field of view.
The correct choice of CCD camera is very important, because it directly affects the composition of the system at the end of the system monitor to see the effect of the monitored surface painting can meet the system design requirements (in terms of the picture range or image details), so the correct choice of camera lens can make the system to get the most optimal design and can get a good monitoring effect.
